During this time, changes in maize leaf angle and size have altered plant architecture, allowing more efficient light capture as planting density has increased. Through a genome-wide association study (GWAS) of the maize nested association mapping panel, we determined the genetic basis of important leaf architecture traits and identified some of the key genes. Overall, we demonstrate that the genetic architecture of the leaf traits is dominated by small effects, with little epistasis, environmental interaction or pleiotropy. In particular, GWAS results show that variations at the liguleless genes have contributed to more upright leaves. These results demonstrate that the use of GWAS with specially designed mapping populations is effective in uncovering the basis of key agronomic traits.","is_dataset_classified":null,"base_score":6.992096427415888,"endowment":6.992096427415888,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21217756","pmcid":null,"openalex_id":"https://openalex.org/W2096808786","authors":[],"funders":[{"funder_name":"National Science Foundation","grant_id":"0321467","title":"Molecular and Functional Diversity in the Maize Genome"},{"funder_name":"National Science Foundation","grant_id":"0638566","title":"High Density Scoreable Markers for Maize Trait Dissection"},{"funder_name":"National Science Foundation","grant_id":"0703908","title":"Gramene: A Platform for Comparative Plant Genomics"},{"funder_name":"National Science Foundation","grant_id":"0820619","title":"Genetic Architecture of Maize and Teosinte"}],"total_grants":4,"fwci":47.2289,"citation_percentile":0.99919482,"influential_citations":0,"citation_trend":[{"year":2012,"count":65},{"year":2013,"count":77},{"year":2014,"count":81},{"year":2015,"count":85},{"year":2016,"count":77},{"year":2017,"count":81},{"year":2018,"count":77},{"year":2019,"count":72},{"year":2020,"count":90},{"year":2021,"count":112},{"year":2022,"count":73},{"year":2023,"count":45},{"year":2024,"count":55},{"year":2025,"count":40},{"year":2026,"count":22}],"oa_status":"closed","license":"Springer TDM","oa_locations":[{"url":"https://doi.org/10.1038/ng.746","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/21217756","host_type":"repository"},{"url":"https://dx.doi.org/10.1038/ng.746","host_type":""}],"fields_of_study":["Genetic Mapping and Diversity in Plants and Animals","Genetic and phenotypic traits in livestock","Genetics and Plant Breeding","0301 basic medicine","0303 health sciences","03 medical and health sciences"],"mesh_terms":["Chromosome Mapping","Zea mays","Epistasis, Genetic","Genetic Linkage","Genetic Variation","Genes, Plant","Plant Leaves","Chromosomes, Plant","Quantitative Trait Loci","Genome-Wide Association Study"],"keywords":["Biology","Pleiotropy","Genetic architecture","Genome-wide association study","Epistasis","Genetic association","Association mapping","Quantitative trait locus","Genetics","Gene","Phenotype","Single-nucleotide polymorphism","Genotype","Genetic Linkage","Quantitative Trait Loci","Chromosome Mapping","Genetic Variation","Epistasis, Genetic","Genes, Plant","Zea mays","Chromosomes, Plant","Plant Leaves"],"sdg_mappings":[{"sdg_number":2,"sdg_label":"2.
